Oats Idli is a healthy and nutritious version of the traditional idli. It is made by replacing a portion of rice with oats, which adds fiber and nutrients to the dish. The batter is prepared by grinding oats, rice, and lentils together, and fermenting it overnight. The fermented batter is then steamed in idli molds until cooked. Oats idli is a perfect breakfast option for those looking for a low-calorie and high-fiber meal.
